2.5-5 deep table at full tilt...river play after missed semi bluff

[Neuman101]

So villain seems standard...he bought in full at 2.50-5 NL and i assume he can lay down a hand- his bets on this hand seemed fishy the whole time...betting out on flop i put him on a huge range of draws and weak aces. I didnt really want to raise flop because it prolly lets him play his hand correctly and fold...i was fairly sure i could still rep a big hand by calling plus i had a very big draw... When he bets out on turn, this looked like perfect time to semibluff...i really didnt expect him to bet out on river...what do people make of this and how do u people act...smelled like a blocking bet to me, could be inducing a bluff...what do people think of hand so far and what is best river action...what is best bet size if we bluff raise river?

Raise flop please. Turn raise is also too small. River i dont think a shove is very believable.

What hand besides a draw would you call this flop and raise turn?

wtf? play perfectly? you only have like 50% equity against an ace. you WANT him to fold since youre probably not getting paid off enough if you hit a club.

deepstacked i think i vary my play a lot more and would certainly call sometimes with set or AK or 76...i def agree with donk magic that i want him to fold most of the time, but when i can put him on such a narrow range, i dont mind going further in the hand with him bc i had position and could rep a wide range of hands...
